Chapter 1 Introduction

Thank you for buying the Advantech PCM-3780. The PCM-3780 is a general purpose multiple channel counter/timer card for the PC/104 bus. It targets the AM9513 to implement the counter/timer function by CPLD. It provides two 16-bit counter channels and 24-ch digital TTL I/O.

The I/O bits are divided into three 8-bit I/O ports: A0, B0 and C0. You can configure each port as either input or output via software. The power- ful Advantech-designed counter functions fulfill your industrial or labo- ratory application needs.
